The most important recommendations for safe everyday card use

Keep your PIN secret: cover the keypad when using the card, do not make a note of your PIN or give it to others

Do not get distracted when using the card. If you are unsure, cancel the transaction immediately using the Stop button.

If your card is lost, stolen or withheld by an ATM, or if you suspect it is being misused: have the card blocked

Secure cards

PostFinance equips all PostFinance Cards with a microprocessor chip. This complies with the global EMV standard for payment card security.

The technology used in EMV chips provides effective protection against copying and tampering.

Secure PIN

PostFinance sends PINs to cardholders separately from their cards. PINs are protected by a security envelope when sent through the post. PostFinance uses an effective security procedure to protect PINs at all times.

Cards with the contactless payment function and the digital PostFinance Card can be used in stores to make payments for amounts of up to CHF 40 without having to enter your PIN.

Secure infrastructure

All payment data is protected during transmission. All PostFinance’s computer networks are equipped with an effective firewall that constantly monitors data traffic. PostFinance also monitors defined card transactions for unauthorized withdrawals and contacts the customer concerned in suspicious cases.
